Product Description

From the Manufacturer

The fully modular cabling system allows you to use only the cables you need.

The revolutionary AX1200i is the first desktop PC power supply to use digital (DSP) control and Corsair Link to bring you an unprecedented level of monitoring and performance customization. The DSP in the AX1200i makes on-the-fly adjustments for incredibly tight voltage regulation, 80 PLUS Platinum Efficiency, and clean, stable power.


Real-time monitoring and control with Corsair Link
Monitor and control your AX1200i with Corsair Link Dashboard (larger image)

Put the AX1200i under your control by connecting it directly to a USB header on your motherboard with the included cable, or to a Corsair Link Commander (available separately). Then, download the free Corsair Link Dashboard software for unrivaled power supply monitoring and control options.

Monitor power input and output, efficiency, fan speed, and internal temperature, directly from the Windows based application. Or, take it to the next level and set up and modify fan speed profiles, or even select from virtual “single rail” or “multi-rail” software modes, with selectable OCP points.

Stable and Reliable Power Delivery

DSP-controlled, real-time voltage regulation helps ensure that your valuable components receive clean, stable power.

Less Heat and Lower Operating Cost
(larger image) (larger image)

The extreme efficiency of the AX1200i earns it coveted 80 PLUS Platinum certification. Less wasted power means minimal excess heat. This can reduce the strain on your other components, and it can save you money over the long run in the form of lower power bills.

Quiet Operation at low loads

Super-high efficiency has another benefit: silence. The thermally-controlled fan doesn't even spin at low loads. It's ideal if you're building a quiet PC or you just want to reduce the amount of ambient noise in your life.

Features

Advanced Fan Design

An ultra-quiet, 140mm double ball-bearing fan delivers excellent airflow with exceptionally low noise levels by varying fan speed in response to temperature.

The AX1200i is so efficient that the fan doesn't spin up until you're pushing your system hard. And, fan speed thresholds can be adjusted with Corsair Link.

Are you used to checking to see if the fan spins to verify if your power supply is working? No worries. AX1200i has a self-test switch to verify proper functionality before you install.

Superior components and better engineering for excellent performance and protection
  • High-quality capacitors provide uncompromised performance and reliability.
  • Active Power Factor Correction (PFC) with PF value of 0.99
  • Over-voltage, under-voltage, over-current, and short circuit protection provide maximum safety for your critical system components
  • Engineered to meet maximum power output at a server-grade 50°C temperature rating.

AX1200i provides a dedicated single +12V rail, with configurable virtual "single-rail" and "multi-rail" software modes.
